Randomized Controlled Trial Comparative Study
Comparison of High-voltage- with Standard-voltage Pulsed Radiofrequency of Gasserian Ganglion in the Treatment of Idiopathic Trigeminal Neuralgia.
Although pulsed radiofrequency treatment (PRFT) has been used to treat trigeminal neuralgia (TN) safely, satisfactory improvement is lacking. Recently, much attention has been paid to the PRFT dose and intra-operative parameters. It has been reported that high-voltage PRFT could significantly reduce discogenic pain. ⋯ The effective rate in the standard-voltage group decreased to 19% at 1-year postoperative, while in the high-voltage group remained at 69% (P = 0.000). No significant side effects were detected in both groups. In conclusion, CT-guided high-voltage PRFT is an effective and safe interventional therapeutic choice for idiopathic TN patients.

Multicenter Study
Validation of the Short Form of the Brief Pain Inventory (BPI-SF) in Spanish Patients with Non-Cancer-Related Pain.
The Brief Pain Inventory (BPI) is a widely used pain measurement tool. There are 2 versions, the BPI Long Form (BPI-LF) and Short Form (BPI-SF), which share 2 core scales measuring pain severity and pain interference but which use different recall periods (24 hours vs. 1 week). To date, the BPI-SF has not been validated for use in Spain. ⋯ Substantial improvements were seen on both subscales after 3 months of treatment (ES of 1.76 for pain severity and 1.51 for pain interference). Recall period did not noticeably affect scores; ICCs (95% CI) between the long and short versions were 0.946 (0.938 to 0.954) and 0.929 (0.919 to 0.939) for the severity and interference subscales, respectively. The Spanish version of the BPI-SF is a valid and reliable instrument to measure pain severity and interference.

Chronic noncancer pain influences patient's quality of life and their ability to cope. Pain relieving medication and other specific treatments commonly integrated in biopsychosocial rehabilitation demonstrate modest benefits in pain relief and improved functioning of individuals. Spiritual care, covering the fourth dimension provides insight, inspires hope and purpose, and is thought to mediate mental and physical health for patients. This study explores the need for its inclusion in interdisciplinary pain rehabilitation and describes the requirements and test environment for evaluation. ⋯ Active coping seems beneficial for maintaining positive long-term outcomes of interdisciplinary pain rehabilitation Spiritual care may be conducive to active coping. Further research is warranted to explore the additive value of this spiritual care in the context of a multidimensional care pathway.

Observational Study
High Prevalence of Neuropathic Pain Features in Patients with Knee Osteoarthritis: A Cross-Sectional Study.
The present epidemiological research evaluated the prevalence of neuropathic pain characteristics in patients with painful knee osteoarthritis (OA) and the plausibility that such neuropathic features were specific of OA. ⋯ A relevant proportion of patients with chronic pain associated with knee OA featured neuropathic pain qualities that were not explained by other conditions. The present research has provided reasonable epidemiological grounds to attempt their definite diagnosis and classification.

Several studies have documented increased cardiovascular risk factors, particularly hypercholesterolemia, in the migraine population with respect to controls. However, no studies have investigated the possible relationship between headache severity parameters and lipid serum levels. ⋯ This study shows a significant positive association between migraine frequency and intensity with total and LDL cholesterol, demonstrating for the first time a significant reduction of these lipid parameters after migraine prophylaxis. However, in view of the retrospective design of the study and the small population size, these results should be considered as preliminary, to be confirmed by future prospective controlled trials.
